OBJECTIVE The Brief International Classification of Functioning, Disability and Health (ICF) Core Sets for chronic low-back pain (cLBP) have included the three body functional categories sensation of pain, muscle functions, and emotional functions. As the latter two categories represent umbrella terms, the objective of this research was to identify those(More)
OBJECTIVE Dynamometric trunk muscle strength and endurance tests are performed widely within the rehabilitation management of chronic low back pain. The aim of this study was to examine the accuracy and long-term reliability of these measurements in patients with chronic low back pain. DESIGN Cross-sectional study. SUBJECTS Thirty-two patients with(More)
OBJECTIVE To determine the short- and long-term test-retest reliability of maximum isometric trunk moment measurements in healthy volunteers over 50 years of age, to compare these results with those from volunteers younger than 50 years, and to test whether volunteers' anticipatory emotional state affects the precision of these measurements. METHODS(More)
To examine whether or not median frequency surface electromyographic (MF-EMG) back muscle fatigue monitoring would be able to identify alterations in back muscle function in elderly muscles, if a protocol was used that allowed optimum standardization of the processes underlying electromyographic fatigue, and whether these tests were reliable from day to(More)
OBJECTIVE To investigate the short- and long-term reliability of isometric trunk strength measurements in patients with chronic low back pain in different age groups. DESIGN Test-retest reliability study. PATIENTS A total of 210 patients (age groups 18-39, 40-59 and 60-90 years). METHODS Patients performed testing at baseline, 1-2 days (day 2) and 6(More)
The root mean square surface electromyographic activity of lumbar extensor muscles during dynamic trunk flexion and extension from a standing position and task specific spine ranges of motion objectively assess muscle function in healthy young and middle age individuals. However, literature on neuromuscular activation and associated spine and hip kinematics(More)
